Changes in Microbial Status From Dentate, Edentulous and After Dental Implant Placement
Trial Parameters
Brief Summary
The objectives of this study are to analyze the oral microbiome modulations occurring during the transition from partial (with some residual teeth) to full edentulous (without remaining teeth) status and implant placement in subjects affected by severe periodontitis; to evaluate if microbiome changes in relation to the used of different implant material/surface; and to assess the variance of the changes to determine the sample size for future longitudinal prospective studies.
